X90-OPUS

Have fun! It's a blast to use, especially the download and submit to OPUS part. WoooHooo! 😉

Help me out here. You bought a single unit. It is dual freq, static. So, on any given job you can do an opus, and put it on SPC, with 2+ observations? And, you can do this in short time... maybe 2 20 min observations.

Am I getting it?

It seems to me that an RTK unit, like JAVAD has would simply be better. Like comparing a great bicycle, (the x 90) against a 650 Suzuki, crotch rocket.

Thanks

Customer service is bullet proof too.

Edit for Nate: mine is RTK too, more like a Hawg.

Nate:

It is bang for the buck. It would be nice to have an RTK unit but they are of limited use under the trees and cost a lot. So 2 X-90 OPUS units equals one 20-30 minute setup for control or you can buy their software and do some fast static if you "book it".

I believe that CHC may be a Chinese big boy as they seem to have some pretty modern manufacturing plants.

If Mark Silver says it is good you know it is the thing to buy.

Check out the torture test, the language is of no use but you certainly get the idea.

Nate,

Yes, it is strictly for Static and Rapid-Static OPUS solutions. CHC also makes an RTK unit, but it's a LOT more money. Same for the Javad. The Javad transmitter-less base is about a hundred bucks more than the CHC.

Rapid-Static is 15 minutes-2 hours. Static is 2 hours-48 hours. (According to the OPUS site.)

My purpose? Learning. I want to learn the ins and outs of Low Distortion Projections in Civil 3D and Trimble Geomatics Office. I need some real data to play with. I've spent a lot of time at YouTube University and the Forums, but now it's time to pop open the hood and scrape my knuckles. (a Joe Bouza-ism)

Yikes!

I think that demo unit could go real cheap now! Sheesh!

The lights were on, but was it still making a position? Never saw any data come out of it.

Might be good to get a translation.

It was blinking in sets of 5, so it was tracking 5 SV's. Whether the antenna inside was still in its original location, who knows.

Dave

Thanks. I guess it is the new entry level.

Nate,
Your fellow Arkies have gone through OPUS Projects Training. Thanks to Steve C. and B. Ward. My two X90 units let me SHARE with NGS, USACE and my other PALS. The X90 let's me play in the Big Times. I've rented out my x90 at $162.00 a day with a 10 day min. Bought another.. Afor long Montgomery County will have many FEMA, USACE, and NGS marks to constrain to

DDSM
(is there any of the Pegasus in your yard?)

I've got my eye on the six receiver "campaign kit" as soon as end of fiscal year spending season rolls around.

Within the next 8 to 10 months, you will possible see. Some of the OPUS X90 GPS units in use near Montgomery County, Arkansas. There some big holes in the GEOID Model in that part of the state, in a height mod project. If you happen across any NGS Benchmarks in your area, let us know and we will try to include them in the project.

We have 2 of the OPUS X90 GPS units and they provide a lot of bang for the buck. They really work well with OPUS Projects. If we can get NGS to turn on the share feature in OPUS Projects it will be the best way to process long baselines with multiple receiver types.

One option that I recommend with the OPUS X90 is the heavy duty power cord. We are going to run ours on secure points for weeks at a time, and I don't want to leave the download cable out in the weather for that long so we ordered the heavy duty power cords.

When you get back some results, get some XML back and get my converter program see how it compares with the results mine gets. I've had little live data to compare it to.
E.

BigE,

Will do. My X90 is out cooking right now, as we speak.

Dave

While reading the manual for the OPUS X90, I noticed instructions for how to use it as an RTK base, only with a here position. That could really cut the cost of an RTK system.

Steve,

A Base needs to communicate corrections to the Rover. The X90 doesn't have a transmitter. Price goes way up for one that does.

Dave

Does it come with a post-processing software or is it strictly designed for OPUS and PPP maybe?

Don't for get the hoisin sauce! 🙂

James,

Designed for OPUS, but there are several other options for Post-Processing:
